Answer:

13 hours

Step-by-step explanation:

Let y = the total cost

let x = hours

y = 4x + 5      5 = the one time fee of the jacket  and the parking

57 = 4x + 5  Subtract 5 from both sides

52 = 4x  Divide both sides by 4

13 = x

In the given triangle :

The coordinate of T is ( 2, 10 )

Triangle TUV will be dilated by a scale factor of 2

The most appropriate choice for tangent to a curve will be given by-

[tex]3x + 2y = 73[/tex] is the required equation of tangent.

What is tangent to a curve?

Tangent to a curve at a point is the straight line that just touches the curve at that point.

Equation of tangent to a curve at a point [tex](x_1, y_1)[/tex] is given by

[tex]y - y_1 = \frac{dy}{dx}|_{(x_1,y_1)} (x - x_1)[/tex]

Here,

y = B(x), B(25) = -1, B'(25) = -1.5

Equation of tangent =

[tex](y - (-1)) = -1.5(x - 25)[/tex]

[tex]y + 1=-1.5x +37.5\\y + 1 = -\frac{3}{2}x + 37.5\\2y + 2 = -3x + 75\\3x+2y = 75-2\\3x+2y=73[/tex]

given that,

54 offices are currently rented

and it represent 30% of the total unit

to get the total offices in the building

let the total offices be x

30% of x = 54

30/100 X x = 54

cross multiply

30x = 5400

dividing both sides by 30

30x/30 = 5400/30

x = 5400/30

x = 180

therefore the total offices in the building is 180

Equation of the line passing through the point (-6,-3) and perpendicular to  the line passing through (-2,7) and (6,5) is y = 4x -19.

First we will find the slope of the line passing through (-2,7) and (6,5).

Slope of the line = (5-7)/(6-(-2)) = -2/8 = -1/4.

We know that,

Product of the slopes of two perpendicular lines = -1.

Let the equation of the line we have to find be y = mx + c.

Slope will be m.

Hence, we can write,

m*(-1/4) = -1

m = -1*(-4/1)

m = 4

Putting (6,5)  and m = 4 in y = mx + c , we get

5 = 4*(6) + c

5 = 24 + c

c = 5 - 24 = -19

Hence, the equation of the line is:-

y = 4x -19

The total distance of the fun run is 7 9/10 miles and it can be written in the simplest fraction form.

Fraction:

The fraction is the part of the whole thing.

For example, a cake is divided into four equal pieces, then each piece is represented by ¼.

Given,

A school is organizing a fun run. The fun run involves a 4 1/2 mile run around the field, then a 3 2/5 mile run back to the school.

Now, we need to find the total distance of the fun run and we have to write it as simplest form.

First we have to convert the given fraction into simplest fraction then we get,

=> 4 1/2 = 9/2

=> 3 2/5 = 17/5

Now , we have to add these to fraction in order to get the total distance,

=> 9/2 + 17/5

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(9/2, 17/5) = 10

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

=> 45/10 + 34/10

=> 79/10

While we convert this into mixed number then we get,

Answer

The amount invested at

Step-by-step explanation:

The total amount invested is $5000

Let x be the investment at 5%

Let y be the investment at 15%

Mathematically, this can be expressed as

x + y = 5000 -- equation 1

Since the first part of the investment is invested at 5% and the second part is at 15%

0.05x + 0.15y = 540 --------- equation 2

The systems of equations can be solved simultaneously using the substitution method

x + y =5000 ----- equation 1

0.05x + 0.15y = 540 ------ equation 2

Isolate x in equation 1

x = 5000 - y

Substitute the value of x into equation 2

0.05(5000 - y) + 0.15y = 540

Open the parenthesis

250 - 0.05y + 0.15y = 540

Collect the like terms

-0.05y + 0.15y = 540 - 250

0.1y = 290

Divide both sides by 0.1

0.1y/0.1 =290/0.1

y = $2900

Recall that equation 1 is

x + y = 5000

y = $2900

x = 5000 - y

x = 5000 - 2900

x = $ 2100

Hence, the investment at 5% is $2100 and the investment at 15% is $2900
